MEASURING DEVICE.

Application filed ma 19, 1926. Serial no. 110,299.

This invention relates .to certain novel improvements in measuring devices and more particularly to av device for locating hinges upon doors and door jambsand the like and has for its principal object the provision of an improved construction of this character which will be highly efficient in use and economical in manufacture.

Among the salient objects of the invention is the production of a measuring de-- ing sleeves slidably receiving the staff and marking edges extending outwardly from certain ends of the bearing sleeves to provide substantially flat opposite edgeportions adapted for engagment \viththe transverse edges of a hinge leaf whereby the marking elements-can be accurately spaced apart according to the length of the hinge leaf.

Vi e are aware of the fact that prior to our invention there are devices now on the market, for the purpose, which include marking elements, defining marking edges. These devices have been found unsatisfactory for the reason that the edges are so disposed in opposite relation as not to per mit accurate gauging of the hinge leaf. This is by reason of the fact that the mark ing edges are not so constructed as to provide flat edge portions which are adapted for engagement with the transverse edges of a hinge leaf, 1

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts to be hereinafter describedand claimed.

The invention will be best understood by reference. to the accompanying drawings illustrating the preferred form of construction and in which:

Fig. 1 is a typical longitudinal View of the invention showing the same disposed in relation with a door jamb and a door.

Fig. 2 is a fragmentary typical and side elevational view of the upper end portion of the invention.

. tional relation with the end Fig. 3 is a sectional detail view taken substantially on line 3-3 of Fig. 1.

Fig. 4 and Fig. 5are sectional detail views taken substantially on lines 44 and 5-5 respectively of Fig. 1.

Fig. 6 is a fragmentary detail View illus tratlng a hinge leaf disposed upon fiat edge portions ofmarking elements embodied in the invention.

To clearly illustrate the application and utility of our invention we have illustrated in the drawing a door 10 which is adapted to be hinged, through the medium of hinges 11, to a door jamb construction 12 The measuring device A embodying our invention includes a segmental plate 12 adapted to have its outer end portion 13 disposed upon the top edge 14 of the door 10. Suspended from this plate 12, which plate is substantially semicircular in form, is a measur ng staii' B. This measuring staff, Fig. 1, includes an intermediate sectional part 15 of preferably tubular formation and adapted to slidably receive end sectional parts 16 and 17 likewise tubular in form.

By constructing the sectional parts markmg up the staff Btubular in form and by sl dably associating the end sectional parts With the intermediate sectional part, it is manifest that the measuring device will be comparatively light and that the device can be collapsed to permit the same to be placed in confinementin a-tool box (not shown) or in a leather glove (not shown).

The end portions 18 of the intermediate sect onal part 15 include longitudinal slits 19. These end portions 18 carry collars 20 including-set screws 21 which are adapted to. be threaded into bearing relation with adjacent portions of the end portions 18 for hearing the end portions 18 into fricsectional parts 16 and 17.

The sectional parts making up the staff B adjustably carry marker elements C. These marker elements are each secured in an. adjusted position longitudinally ,of the sectional part with which it is associated through the medium of a set screw 22. Each of these marking elements defines an annular bearing sleeve 23 and an annular marking edge 24 which extends outwardly from one end of the bearing sleeve to define a substantially flat edge portion 25 for reasons hereinafter understood.

In use, when it is desired to locate the hinge the hinge 11 is disposed with one of its leaves 11 arranged between adjacent marker elements 23 as shown in Fig. 6 of the drawing; These marking elements are then adjusted toward the hinge leaf 11' until their fiat edge portions 25 bear upon the tranverse edge portions 25 of this hinge leaf. After the marking elements have been properly adjusted the same are secured in adjusted position through the medium of the set screws 22. The staff B is then disposed longitudinally of one of the longitudinal edges 10' of the door 10 with the plate 12 enga in the top edge 14 of the door. Thesta ll E is then manually pressed toward the longitudinal edge of the door to bring the marking elements into engagement with the longitudinal edge 10. After this has been accomplished the staff B is rocked transversely of the edge 10' to cause the marking edges 24 of the marking elements to 0 erate upon the edge 10 of the door to de ne the lines 12.

When the measuring device is used to locate the hinges on the door jamb 12" the stafl B is disposed longitudinally of the side 13 of the door jarnb 12* with the plate 12 in abutment with the top portion 14' of the head jamb 15' of the door janib 12. After this has beenaccomplished the staff B is gently forced toward the side 13 to bring the marking edges 24 into operative position whereby when the staff B is rocked transversely of the side 13' the marks 16 will be defined. These marks 12 and 16 locate the point where the hinges 11 are to be located.

While we have illustrated and described the preferred form of construction for carry ingour invention into effect, this is capable of variation and modification without departing from the spirit of the invention.

We, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail ourselves of such variations and on come within the scope of the appended claims.

The invention having been set forth, what we claim as new and useful is:

1. A measuring device including an elongated member, pairs of marking elements adjustable longitudinally of the elongated member, each marking element comprising a sleeve and a marking edge extending transversely thereof at one end, the markin edges of each pair being disposed towar each other and providing opposite fiat edge portions for engagement with transverse edges of a hinge, and means for scour the marking elements in an adjusted position with respect to the elongated member.

2. A device of the character stated including an adjustable extensible member having marking edges 'exten g transversel o said sleeves and adapted to be dispo toward each other in adjustable relation whereby when said member is rocked about said position locating element said marking elements will engage the edge of said door or said jamb so as to mark indicating lines thereon.

In testimony whereof we afix our signatures.
